Problems of energy supply of the main consumers of distribu-tive networks of Iraq

Abstract

Abstract The main purpose in this paper to study the main features of the distribution network for Iraq, which showed that the distribution network is physically and morally obsolete. Analyzing of electrical distribution networks is considered of highest priority at the present time in Iraq. This paper presents efficient practical methods for calculating the main parameters of the distribution network based on scientific and practical fundamentals. In this work the analysis is based on the advanced RasterWin3 software as a tool for the calculation of a basic parameters for distribution network performing the required analysis. RasterWin3 software is practical and efficient analysis software used by many electrical companies worldwide. The distribution network calculation was implemented (11/33) kV. The calculation results showed that the voltage deviation exceeds the maximum permissible value and is 12% in normal mode and 40% in emergency mode. Power losses in the branches of the power system of Iraq reach 20% of the consumed electricity. This is justified by the low quality of electricity and overload of the power supply system.
